Hi all - I've been using my 64-bit R3000Z with Gentoo (mostly) happily now for just shy of two years. I say "mostly" since the laptop has been overheating recently and I was wondering if others have the same experiences.
Several things happened recently around the same time, so I'm not sure if any one thing has led to this: 1. My original power supply "brick" unexpectedly died. I was desperate and bought a Targus generic power supply (a shocking $100 at CompUSA). This power supply was rated at 95W - somewhat worrying since the original power supply seemed to pump out 120W max. The Targus nonetheless had the Presario 3000 listed as "guaranteed compatible with". I used the Targus for about two weeks while I ordered a "proper" replacement (I think from ATBat or something - $79 - it was rated exactly as the original power supply; same size, too). 2. Around about this time I also upgraded to kernel 2.6.16 (I only mention since perhaps, just perhaps, the 2.6.16 kernel has some power issues - pretty unlikely, I know). Anyway, the Targus would get much hotter than the original brick ever did. And I mean *much* hotter - almost too hot to touch. I figured the laptop was drawing more power than the Targus' rated 95W. Also, the laptop itself suddenly seemed to run at a much higher temp. At full clip (2.4 GHz), 'gkrellm' would report temps in the range 72-78C. Both cooling fans would be active at full. The laptop had rarely gone above 70C with the old power supply. If I cycled the CPU down to 2.0 GHz, the temp would drop down about 10-15C. I figured all would be well with the new power supply, but I've been using this for a few weeks now, and the laptop is running just as hot. In fact, it has happened twice now while crunching MatLAB that the temp hit 89C and then the laptop promptly shut down. I've been using MatLAB on an almost daily basis on this laptop, so it's not as though suddenly my usage patterns have changed. Does anyone have any insights? Is the running temp at 2.4 GHz somehow a function of the power supply, too? Or are these completely unrelated and the laptop is showing its age - first it's old power supply gave the ghost and round the same time the fans themselves are losing their efficiency...
